RALPH: Meta-reasoning

Description

• The Metalevel arbitrator determines which the reasoning methods implemented by the four execution architectures is the most appropriate in the current situation
• Its choice at any point will be influenced by events in the environment, resulting in environmentally-constrained reasoning
• The Metalevel also has knowledge about the performance of each execution architecture with respect to amount of computation time provided
• This allows the Metalevel to determine when the utility of additional computation (by the execution architectures) falls below zero, at which point the Metalevel stops computation and outputs the current best action
